  1. Design ReviewNovember 11, 2003 Projects: Interactive Campus Map (ICM) Adjustable Book Shelf (ABS) Global Positioning System Device for the Visually Impaired (GPS-DVI)

  2. ICM Interactive Campus Map • Objective: To help students with physical disabilities locate the best accessible path between campus locations by drawing a map

  3. Group Members • Jeff Turkstra – Project Leader / Programmer • Abdul Zahid – Technical Programmer • Avirul Sharma – GPS coordinator • Vishnu Jaju – Graphic Designer/Multimedia

  4. Semester Goals • Install functioning Kiosk in MSEE Building • Expand area, and plan improvements • Better map images • Actual distance calculations • Voice recognition & synthesis

  5. Initial Tasks • Kiosk has to be picked up from machine shop and building services contacted regarding installation - DONE • Computer Kiosk has to be configured and setup for user access - DONE • Obtain more GPS coordinates for all of campus - PARTIALLY DONE • Get user feedback – Plan new features - PARTIALLY DONE

  6. Web-Interface • Facilitates channeling of the user input data to the best path implementation routine • Simple and easy to use • Easy to maintain for future semesters • Accessible via home computers, not just kiosk

  7. Nodes in the Map

  8. Node Database • Database example • For GPS coordinates (Latitude, Longitude)

  9. This Semester • Kiosk is ready (but ICM software is still “under construction”) • Larger, more detailed map integration is in progress • Coverage area has been significantly expanded over last semester • Resolved compilation errors with core source code

  10. Coverage Area • Engineering Mall (from last semester) • Area surrounding (and including) BRNG, MATH, and CL50 • Clock tower area (SC, CS, PSY) • “Chemistry” area (WTHR, BRWN, GRIS, HEAV, etc)

  11. Prototype Ideas • Work has been done on planning methods to interface with GPS-DVI • Theoretical design for mysql driven PHP interface permitting the “posting” of current GPS coordinates and destination coordinates to the server, which would in turn generate and send back a map with text based turn-by-turn directions

  12. Semester Timeline

  13. Adjustable Book Shelf Team Members : Sandeep Nandy (Project Leader) Ankit Dhawan Vineet Alva Shohei Shibata Rayelle Duncan

  14. Agenda • Timeline • Design Parameters • Turn Shelf Concept • Slide Down Concept

  15. Timeline

  16. Design Parameters • Cost less than $500 • Requires very little muscle force by user • Hold at least 8 – 10 books • Makes use of current dorm shelving unit • All books are attainable from a seated position

  17. Turn Shelf 3-D view

  18. Turn Shelf Side View with dimensions

  19. Turn Shelf Accomplishments • Dimensions and clearances determined • CAD models completed • Book Capacity determined (12 books 2” thick) • Max weight it will experience ~50 lbs

  20. Turn Shelf Uncertainties • Use of Motor with belts • Pros: Will require little or no muscular force by user • Cons: High Cost, higher chance of failure by parts • Use of flat metal coil springs • Pros: Low cost, low risk of failure • Cons: Anchorage of string, will require slight initial force by user

  21. Slide Down Bookshelf Design • An adjustable bookshelf that fits inside the existing shelf. • Slides down at an angle onto the desk.

  22. Accomplishments • Basic mechanisms and components of the bookshelf has been designed • CAD drawing and dimension drawings are complete • Capacity and loads have been approximated

  23. Pros More space Easier access Less complicated motions Cons Requires more forces Possibly requires electrical assistance Noise Cost Space Pros and Cons of Sliding Design

  24. Future Plans • Means of lifting the shelf back up needs more research • Safety Measures • Counterweight idea is being considered • Every component will be designed to more details • Decision to be made on our final solution, as well as contacting University Residences for their input

  25. GPS-DVI Global Positioning System Device for the Visually Impaired • Team members : • Guneet Chadha • Sivanit Ratanadib • Ryan Hicks • 4. Howard Lityo

  26. Introduction GPS-DVI : Team project that involves the development of a handheld device, incorporating a PDA with a GPS receiver which will aid students who are visually impaired in navigation around the campus.

  27. Overview • Project partner meeting • Creation of Sub-Groups • Assimilation • Research • Current State

  28. Project Partner Meeting • Requirements of the device • Interact with GPS reciever • Voice output • 90 degree turns • Tactile overlay • Telephone like keypad • Shortest Path Algorithm

  29. Creation of Sub-groups

  30. Assimilation • Retrieval of equipment • Determine previous work accomplished • GUI • Building codes • Device driver (does not compile) • Determine work to accomplish • Device Driver • Algorithm • Voice Output

  31. Research • Met with EPICS & Mobility TA’s • Explanation of how to use Microsoft Embedded Visual Tools 3.0 • Suggested that we buy device driver (dll) • Researched GPS Receivers • Teletype #1358 (no dll exist) • Received manual • Teletype #1658 (a dll exist) • Pretec Compact GPS & Compact GPS-LP • NavRoute HP-610PC (no dll exist) • TextAloud MP3

  32. Current State • We have obtained our PDA! • Verified working function of GUI • Received streams of GPS data • Configuration of GPS receiver in progress • Plan to integrate building codes with GUI • Continue to debug the device driver code from Fall 2002

  33. Questions, Comments, Suggestions
